Gretna, NE Working for Verizon, General Excavating recently completed work on nearly four miles of fiber relocation as the Nebraska Department of Roads widens a section of Highway 6 in Sarpy and Douglas Counties from two to four lanes. Construction on this heavily traveled road required a considerable amount of coordination as crews moved the fiber route across Highway 6 at several locations, exposed existing utilities, set hand holes, and dug bore pits. Roads, streams, and railroad tracks were crossed using directional boring. "One challenging railroad crossing required a bore over 60-foot deep," commented Dennis Willeford, foreman for General Excavating.
Starting in June, the route was staked as construction took place in the public right of way. A vibratory plow was used to install approximately 18,000' of the 2-inch HDPE duct while horizontal directional drilling was utilized to construct almost 3,500' of conduit. Installation on a fiber project includes burying the conduit, blowing a string through, pulling the fiber, and then splicing the fiber. On July 14th, the hot cut was completed, connecting the new fiber to existing fiber. The fiber from the old route was pulled and put on reels for reuse on other Verizon projects. The construction of hand holes, splice pits, concrete replacement, and site restoration were other important components of the project. "I was pleased, the guys ran a safe job on a busy road and kept construction moving along," stated John Kooistra, project manager for General Excavating.
